INTRODUCTION 

One of the problems man has had to contend w tlh 
throughout the history of firearms, has been noise. 
Prior to discharging an unsilenced weapon, some 
shooters have the tendency to flinch in anticipation of 
the muzzle blast, thus affecting accuracy, After dis- 
charge. a bigger problem is the period of temporary 
deafness the shooter experiences. 

Gun noise also attracts attention, and for individu- 
als or small groups of combatants, facing a superior 
force, this could mean detection and disaster.

Disposable Silencers 



Gun noise can be categorized into three major 
categories. 

1. MECHANICAL NOISE 

The noise the w eapon's mechanism makes 
in order to fire a round. 

This noise w ould be least noticeable in a bolt action 
weapon, due to its minimum of moving parts, and 
most noticeable in an open bolt submachine gun t\pc 
weapon or semi-auto weapon. !n real practice, how- 
ever, all three weapon systems have been effectively 
silenced, examples being the MAC 10. 1 1 submachine 
guns and the RUGbR MK I and HIGH STANDARD 
.22 caliber semi-auto pistols. 

2. SONIC CRACK 

The noise a bullet makes when traveling 
over 1100 fps (feet per second). 

When a bullet travels at super sonic velocities there 
will be a sonic crack much like a jet's sonic boom, 
Little can be done to lower the velocity of bullets 
which travel at a much higher level than IKK) fps 
Extensive modifications to the weapon's barrel sys- 
tem would be required. One modification could he 
porting the barrel to release propellant gas before the 
bullet exits the barrel to reduce velocity, i his is 
undesireable in certain calibers as they require a high 
velocity in order to be effective. Case in point is the 
.223 Remington (5,56mm). 

Other calibers which are just slightly above the 
1 100 fps level, as is the case w ith the 9mm luger. can 



Introduction 



he properl) lowered to subsonic levels by handload- 
ing with lighter powder charges or using heavier 
bullets It using .22 long rifle caliber ammunition, try 
to avoid hyper velocity rounds a*, some exceed super 
sonic levels. 

3. MI ZZLE BLAST 

The noise generated by the escape of the 
hot propellant gas. 

Of alt the noises associated with firearms, the most 
significant is the muzzle blast, which is caused by 
escaping propellant gas upon bullet exit from the 
barrel. 

The objective of most silencer designs is tit reduce 
the muzzle blast by preventing the sudden release of 
the hot propellant gas long enough to reduce its pres- 
sure and lower its temperature. 

In constructing any silencer, there are a few points 
that should be eonsidcred first, such as the purpose 
for which the device will be used and the degree of 
silence desired. Ii should he remembered that com- 
plete silence has rarely been achieved, Hor maximum 
effectiveness, a caliber should be chosen that is below 
super sonic velocity and that does not produce so 
great an amount of escaping gas as to make the 
silencer too large and bulky, thus impractical. 

Whenever possible, avoid revolvers as they usu- 
ally can not be effectively silenced due to the escape 
of gas between the barrel and chambers.

CONSTRUCTION 

SECTION 

The following designs were mainly selected for 
(heir ease of construction, material availability, low 
cost, and most important of all. effectiveness. 

The construction of these silencers w ere designed 
to use a minimum of materials, labor and unils. Mate- 
rials vie researched to make the silencer as effective 
as possible, yet easily accessible at any supermarket 
or hardware store. These designs, though they may 
appear crude, where found to be the most basic and 
effective. All conform to the fundamentals of effec- 
tive firearm silencer principles. 



4 



Construction Section 



One important point to bear in mind is that these 
silencers, although very effective, are “disposable" 
silencers, and will lose their effectiveness after a 
few shots. 

One of the main features of these silencers, besides 
their low cost, is their letmlitv. Federal. State and 

lL*> -p 

Local laws prohibit the possesion of anv firearm 
silencing device without a special license. You must 
first apply for the license, then if approved. pay a 
special tax of $200.00 and then proceed to assemble 
your silencer. Thus the design of these silencers are 
such that owning all parts by themselves (DISAS- 
SEMBLED!) i' perfectly legal. ALW AYS remember 
that any ASSEMBI ED device, whether it be impro- 
vised or professional!} made, to reduce the sound 
level of a firearm is illegal without this special 
license. In some states vou are not ttiven a choice, as 
ail sound suppressors are prohibited to private citi- 
zens. Check with your local authorities BEFORE 
construction. 

Although most of the silencers presented in this 
book can be installed to practically any weapon, to 
achieve maximum effectiveness, the author recom- 
mends the use of a ,112 long rifle caliber weapon. 

Experimentation is a ke> element in developing an 
effective silencer. Different diameters, lengths, and 
shapes may have a great effect on the effectiveness of 
any given design. 

(NOTE: Dimensions in this book are sitven as re- 
terences only. Depending on the caliber of your 
weapon, you may require a different length or di- 
ameter or both. )

SCREEN SILENCER 

Here is one tha* is ver> effective for .22 caliber 
weapons. 

2 pieces of screen. 6 inch and 8 inch w ide b\ 

■rf' 

several feet long, some tape and an ordinary lead 
pencil are all the materials required. 

Start with the strip of screen wire six indies wide 
and several feel long and begin wrapping one end 
around the pencil. Continue to wrap the screen wire 
around the pencil until the roll is the same diameter as 
the outside diameter of the barrel on your weapon.

L'sc two pieces of tape in prevent the screen wire 
roll from unwrapping. 

Now sw itch to the strip of screen wire about 8 inch 
w ide. (NOTE: It is suggested that the front end of the 
barrel be taped to prevent it front being scratched by 
the screen.) Keeping one edge flush w ith the front of 
your original roll, let the other edge extend back two 
inches around the barrel. Each time the screen wire is 
w rapped over the front sight, cut a small notch in the 
wire, so that the sight extends through it. and press 
that laser dow n tightly against the layer beneath it. 
Continue wrapping four or five turns until the inner 
cylinder of screen wire is firm!} held to the gun 
barrel. Cut off any excess length of the screen wire 
strip. 

Finally, wrap the outer part of the roll with two 
lay ers of ordinary electrical tape or cloth adhesive 
tape, letting the tape extend back an additional two 
inches on the bare gun barrel to hold the "silencer " in 
place. Remove the pencil before firing.

SOFT DRINK BOT TLE 
SILENCER 

The following design is one of the simplest to 
manufacture, least expensive and yet. one of the most 
effective of all disposable silencers. 

All that is required for construction is an empty 1 or 
2 liter plastic soft drink bottle, a 1 or IV; inch hose 
clamp and some tape. 

The bottle chosen lor this purpose must have a 
reinforcing ring on the bottom portion, this is neces- 
sary to prevent the bottle from splitting upon dis- 
charge. There are several brands of soft drink that 



20 



Soft Drink Bottle Silencer 



have this reinforcing ring, so get one that \ou will 
enjoy drinking. 

This unit is only effective for a few shots, as the 
noise level will increase with each successive shot, 
due to the enlarging exit hole at the bottom of the 
bottle. 

Begin construction by measuring the inside diame- 
ter of the bottle neck w ith the diameter of the barrel, it 
the diameter of the barrel is smaller, bring it up to the 
required size by using electrical tape. iNOTL: W ith 
some weapons you will need to make a slot on the 
bottle neck for the front sight. Make it a tight fit! ). 

Next, slip the I or 1 V4 inch hose clamp over the 
bottle neck and install bottle to weapon. Once the 
bottle is in place, position the hose clamp over the 
tape and tighten damp. (Make sure there is a good 
seal between the tape and inside of bottle neck.) 
Check the from sight siot for any openings, and u-e 
tape, if necessary, to sea) any leaks. 

If desired, use some paint to match the "silencer 
to your weapon's finish.

PIPE AND SOFT DRINK 
BOTTLE CAPS 

A simple silencer can be made using soft drink 
bottle caps. 

Materials required are about 20 bottle caps, a pipe 
in which the bottle caps lit snugly, an end cap for the 
pipe, a l inch or 1 Vi inch hose damp, and some 

electrical tape. 

Start to make your silencer by making a tape bush- 
ing behind the front sight. It should be just slightly 
less in diameter than the inside diameter of the pipe. 

Next, make a slot in the pipe for the front sight. Use 



B ottle C an Silencer 



a jig saw or hack saw to cut the slot and files to smooth 
an} rough edges. The slot must be long enough so that 
there is from inch to % inch of pipe extending past 
the hack of the front sight. 

Install the pipe to the gun w ith the hose clamp in the 
back of the front sight. (Another acceptable method 
for pipe installation is to slot one end of the pipe and 
file a notch to one side. This can then be slipped over 
the front end of the barrel and held in place by twist- 
ing the pipe so that it catches behind the front sight ). 

Proceed b_\ punching and drilling the bottle caps 
using a drill with a larger diameter than the caliber to 
be used. Drill end cap making its hole larger than that 
of the bottle caps. 

NOTE: When constructing this disposable si- 
lencer. it is best to leave the hole through 
the center plenty large to prevent the bul- 
let from striking the silencer, if it should 
become tipped to one side. 

Begin filling the pipe w ith the bottle caps, stacking 
them all in one direction w ith the drilled holes point- 
ing towards the end cap. Make sure the last bottle cap 
has the drilled hole towards the end cap and is half 
way out id the pipe, that way the end cap will push 
against it when installed, holding the caps firmly 
inside the pipe. 

Final l>. place a cleaning rod or any other suitable 
rod through the silencer and into the barrel, this is to 
ensure alignment of the caps with the barrel and end 
cap. Install end cap. Before firing, remove the clean- 
ing rod.

Pipe Silencer 



PIPE SILENCER 

This one looks more complicated than it really is. 

The materials needed for construction are: A piece 
of PVC or an> other type of pipe, about six or seven 
inches tong, with the same inside diameter as the 
outside diameter on your weapon’s barrel. (A diame- 
ter slightly larger will work if tape is used to bring up 
the barrel to a suitable diameter.) A one inch hose 
clamp, a piece of soft rubber, copper scouring pads 
(available at most supermarkets as "CHORE BO't 
PL RE COPPER SCOURING PADS”) and some 
wide electrical tape. 



55 



Disposable Silencers 



Begin construction by drilling the pipe with four 
rows of evenly spaced % inch diameter holes, 90 
degrees apart- The number of holes will be deter- 
mined by the length of the pipe. (Deburr all holes, 
both inside and outside after drilling, ) 

Next, cut a slot for the front sight, using a jig saw or 
hack saw for rough cutting and files to smooth the 
edges. The slot should be long enough so that the pipe 
extends about '/j inch to one inch past the back of the 
front sight. Try to make it as tight a fit as possible. 

Slide the pipe onto the barrel, w ith the front sight in 
the slot. Position the hose clamp behind the front 
sight and close to the end of the pipe. Tighten clamp 
(use tape to bring up barrel to size, if necessary). 
Make sure that the pipe ts snug and tight against the 
barrel to prevent it from wobbling. 

Cut the piece of soft rubber into a disk shape having 
a diameter slightly larger than that of the outside 
diameter of the pipe. With a sharp razor or knife make 
an “X" at the center of the disk. Put the rubber disk 
aside for the moment. 

Cut out the rivet in the copper scouring pads and 
unfold them, this will make it easier to wrap them 
over the pipe. 

Wrap the copper scouring pads (several should he 
used, depending on the length of the pipe), around the 
pipe as tightly as possible and hold them in place with 
the palm of your left hand. Place the soft rubber disk 
w iih the ' ' X ’ " at the center of the pipe hole, and hold 
in place with the forefinger and thumb of your left 
hand. Begin taping around the rubber disk and roll of 



56

copper pad;, with vour right hand, making certain the 
"X" in the rubber disk is still aligned with the hole in 
the pipe, (A simple way to assure alignment is to pass 
a cleaning rod through the “\" and into the barrel.) 
Using wide tape will make the job a lot easier. Extend 
the tape far enough to the front so it will hold the 
rubber disk in place. 

Once the rubber disk is in place, begin wrapping 
back, overlapping the tape as you go. Extend the tape 
back to the front sight covering the whole ' silencer" 
\v ith two layers. Be certain no sections of the copper 
scouring pads are exposed.
